Let's divide 70884 by 21
Our goal is to divide 70884 by 21.

Let's proceed to step 1:
7 divided by 21 is 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Bring next digit (0) of the dividend behind the 7 and repeat the process: 70 / 21

Let's proceed to step 2:
70 divided by 21 is 3 with a remainder of 7.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtract 63 from 70 to get 7.
Bring next digit (8) of the dividend behind the 7 and repeat the process: 78 / 21

On to step 3:
If we divide 78 by 21, we get 3 and a remainder of 15.
Record the quotient 3 as the next digit in the result. 
Result so far: 33.0
Subtract 63 from 78 to get 15.
Grab the next digit (8) from the dividend, add it to 15, then carry on: 158 / 21

On to step 4:
If we divide 158 by 21, we get 7 and a remainder of 11.
Use 7 as the next digit of our solution. 
Result so far: 337.0
If we subtract 147 from 158, we get 11.
Append the next digit (4) from the dividend to 11 and continue with: 114 / 21

On to step 5:
114 divided by 21 is 5 with a remainder of 9.
Record the quotient 5 as the next digit in the result. 
Result so far: 3375.0
Deduct 105 from 114 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 6:
21 goes into 90 4 times with a remainder of 6.
Use 4 as the next digit of our solution. 
Result so far: 3375.4
If we subtract 84 from 90, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 7:
21 can be fit into 60 2 times, resulting in a remainder of 18.
Use 2 as the next digit of our solution. 
Result so far: 3375.42
Deduct 42 from 60 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 8:
When dividing 180 by 21, we get 8 with a remainder of 12.
Record the quotient 8 as the next digit in the result. 
Result so far: 3375.428
If we subtract 168 from 180, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 9:
21 can be fit into 120 5 times, resulting in a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 3375.4285
Subtracting 105 from 120 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 10:
The number 21 fits into 150 7 times, leaving a remainder of 3.
Put 7 as the next digit of the answer. 
Result so far: 3375.42857
If we subtract 147 from 150, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 11:
30 divided by 21 is 1 with a remainder of 9.
Write down 1 as next digit of the result. 
Result so far: 3375.428571
If we subtract 21 from 30, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 12:
If we divide 90 by 21, we get 4 and a remainder of 6.
The number 4 becomes the next digit in our result. 
Result so far: 3375.4285714
The remainder is 6 after subtracting 84 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 13:
60 divided by 21 is 2 with a remainder of 18.
Put 2 as the next digit of the answer. 
Result so far: 3375.42857142
If we subtract 42 from 60, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Our division results in 3375.42857142 with a remaining 1.8e-08.
